摘要
电子探针、扫描电子显微镜、Ｘ射线衍射等测试方法的应用，揭示了碧田金矿床冰长石的存在及其矿物学特征。冰长石的存在及其它地质证据，说明碧田金矿床属于冰长石－绢云母型浅成低温热液贵金属矿床，与附近产出的紫金山酸性－硫酸盐型铜金矿床成因类型不同。两种端员类型浅成低温热液贵金属矿床产于同一地质环境，这在我国是第一个实例。
The adularia associated with Au, Ag mineralization in Bitian gold deposit is identified by Electron Microprobe, Scanning Electron Microscope, and X ray Diffractometer. The existence of adularia suggestes that Bitian deposit belongs to adularia sericite type epithermal precious metal deposit, which is different in genesis type from the large size Zijinshan acid sulfate type epithermal Cu Au deposit located only about 3 km Northeast. Both adularia sericite and acid sulfate type deposits occurring in proximity is the first example in the mainland of China.
